Thankfully, I am armored up pretty good. Spring Creek tested just about everything I've bolted onto my rig, including both bumpers, both sliders, all 3 skid plates, heck I even used the winch. I was struggling to remember the last time I needed a winch in the summer . But a couple of those slams were pretty good, my lower A-arms, skid plates, swaybar links, even driveshaft and pinion looked like I drove through a war zone.
